On hold messages can be recorded for many purposes, such as promoting your business, answering FAQs or announcing important customer service information. It's important to be clear in the message you are trying to get across. Confusion leads to disengagement and reflects badly on the brand. Determining your callers' wait times is necessary to determine the required length of the on-hold message. Making the recording too short can lead to the message being played too many times. This can be repetitive and lose the caller's attention while they hold.
You’ll want to have your office hours in the voicemail so that cleaning customers know when they can connect with you. You don’t have to always be available during all of those times, it’s just the possibility you’ll actually pick up your phone or will be able to give them a call back during those hours. Adding in office hours makes your business sound much more professional. It’s the sign of a more established, well-run company to have business or office hours.

When you create a professional voicemail greeting, it can be a good idea to think about what your callers might want to know. After doing so, you can make a list of points to cover in your voice message; it might also be a good idea to write out the entire greeting on a piece of paper. The ideal message should be somewhere between 10 and 20 seconds, so you may want to time yourself repeating your message before you record it. After composing your telephone message, it can be a good idea to get a second opinion of this greeting so you can make sure it sounds professional. Writing down a voicemail greeting helps prevent mistakes when recording it.
